Fix race when deleting an EFI variable and issuing another EFI command on
the same variable.  The removal of the variable from the efivars_list
should be done in efivar_delete and not delayed until the kobject release.

Furthermore, remove the item from the list at module unload time, and use
list_for_each_entry_safe() rather than list_for_each_safe() for
readability.

Tested on ia64.

The error path path mistakenly called sysfs_create_group() rather than
sysfs_remove_group().  They take the same arguments, so it's easy to
cut-n-paste such a bug.
